help me ID 302 block

[91stang50GT]

I found a block that i may want to use for a future head/cam/intake build but i have no other information about it besides being a 302. These are the numbers on the block:

D10E-6015-AA

Date Code: 2D11

Can anyone tell me if its a hydraulic roller block or not, HO or not, and what it came out of? thanks

IIRC, D=70, 1=year.... so the engine would have been built in '71.

if it was built in the 70s its neither an HO nor a roller block.
